American Institute of
Aeronautics and Astronautics 15 aged in the humidity oven decomposed after 7 days and some samples solidified into a white powder. Samples that were exposed in the humidity oven for only 2 days or 4 days were still liquid, but became opaque. Samples aged in dry air and dry nitrogen environments did not show any signs of decomposing. All aged samples were tested in drop tests with neat WFNA. The solidified samples did not ignite but the samples exposed for only 2 days or 4 days still provided good ignition characteristics. These samples showed a significantly decreased
presence of OH radicals, but all other characteristics were consistent with the neat TEAB. It is interesting that the OH presence can be dramatically decreased, but all other characteristics show no signs of change. The samples aged in dry air and dry nitrogen environments show almost no change in ignition performance.
